TELEGRAPH RECEIVING-INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 355,431, dated January 4, 1887.

Application filed July 24, 1885.

To all whom it may concern:

Be it known that I, WILLIAM ARTHUR, a citizen of the United States, residingat Gainesville, in the county of Alachua and State of Florida, have invented certain new and useful Improvements in a Device for Receiving Telegraphic Dispatches, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in devices or instruments to receive telegraphic dispatches.

The objects of my improvements are, first, to enable telegraph operators to receive dispatches through the mouth, and without the aid of Sounders, indicators, or of impressions upon paper, and thus secure greater secrecy, rapidity, and accuracy in the work of receiving the same; and, second, to relieve operators from the strain and fatigue to which they are subjected by constant listening to catch telegraphic sounds under the method of receiving dispatches hitherto and now in general use. I attain these objects by means of a device or instrument attached to and combined with the ordinary telegraphic telegraph receiving-instrument now used by the \Vestern Union and other telegraph companies, as illustrated in the accompanying drawings, in which- Figure 2 is a side view of my device or instrument as it appears when detached from the telegraphic telegraph receiving-instrument and without an appendage constituting a part of the device, hereinafter described as an ear-press, and Fig. 1 is a side view of my device with the ear-press appendage, and represents the whole device when completed and attached to and combined with a telegraphic telegraphreceiving-instrument.

Similar letters refer to similar parts throughout the several views.

My device or instrument consists of a rod, A, twenty (20) inches long, one-half of an inch wide, and from one-sixteenth to oneeighth (g) of an inch thick, made of pine,poplar, ash, or other light material, and finished smoothly, but otherwise according to the taste of any one, the chief object being to get the correct and proper length and size. One end of this rod is inserted into and covered by a Serial No. 1 2.529. (No model.)

socket or mouth piece, a, made of amber, gutta-percha, or other non-conductor of electricity, the socket being tightly and firmly fitted and fastened on the rod, so as not to shake or rattle. Through the other end of this rod a round hole, 13, is made,ofany size required, to fit a telegraph receiving-instrument. Appended to this rod by a cord, 0, made of silk or other flexible and suitable material, is an earpress, D, made wholly of gutta-percha, with oval-shaped knobs at ends I) b; or the frame may be made of steel or any elastic substance, and the gutta-percha knobs b I) screwed onto the ends of the frame.

My device or instrument is attached to the telegraph receiving-instrument, and adjusted for use, as shown in Fig. 1, and in the following manner: The rod A is placed in position and fastened to the telegraph receiving-instrument by passing a screw, E, through the hole B and through plate F to where it comes in contact with armature G, and is firmly screwed.

In operating and using my device or instrument the socket or mouth piece a is raised to the mouth of the operator, and when the proper and most convenient angle is obtained rod A is made fast in that position. Then the operator should cut out the sounder, if one is used, and place an ear-press over his ears, or in lieu thereof stop up his ears with any soft material that will exclude the penetration of sound, and then place socket or mouth piece a between his teeth. He will then be ready to receive dispatches, and, by the means above indicated, will be enabled to secure a more direct, distinct, and perfect transmission of the electric click or sound of the telegraph to the senses than in any other .manner or way, and thus be also enabled to receive and write out messages or dispatches more rapidly and accurately than by any other means and with more perfect secrecy. The ear-press can be conveniently placed upon or over the cars by opening the knobs b I), pass- 5 ing them behind the neck, and allowing them to press directly over oron the ear behind the cheek-bone. In the absence of the ear-press the ears can be stopped upin the mannerabove stated.

My device precludes all necessity for sounders, indicators, or impressions upon paper in IOO fljgorlr of receiving telegraphic dispatches. Elesfific call-bells may occupy the place now flexed for sounders, and these bells may be cut out when a dispatch or message is'to be taken.

The armature G may be so close to the magnet or plate F that no sound at all can-be heard by an operator by the ear alone in the usual manner, yet when socket or mouth piece a is placed between his teeth and his ears covered or stopped, as abovedescribed,sounds will instantly become round, full, and distinct and make clear and plain impressions upon his senses.

I do not broadly claim transmitting or receiving sounds through the teeth, but limit my invention in this respect to the special devices used by me.

Having thus described my invention, I claim 1. In a telegraph receiving-instrument, a vibrating armature, a contact screw constructed to receive the vibrations thereof and having a flexible connection secured thereto, said connection being knob-ended, whereby the electrical impulses may be received by con- 25 tact therewith and any sensitive part of the body of the operator, substantially as and for the purpose set forth.

, 21 In a telegraph receiving-instrument, a flexible rod adj ustably connected by a set-screw 0 to the receiving-instrument and provided at its end with a tapering knob, the armature of said instrument adapted to contact with said set-screw,whereby the electrical impulses from the line may be received by contact with said 35 knob and the mouth of the operator, substantially as set forth.

In testimony whereof I hereto affix my signature in presence of two witnesses.

\VILLIAM ARTHUR.
